From the looks of it you are doing very well. Not everyone has the "bump" and seven months may be a bit early to see it. For comparison I just had my six month follow up and the PSA was .38. My oncologist was pleased with that number. I have also been taking the hormones as well. My testosterone has not dipped below 45 to my knowledge. It was on the high side of normal to start with. My oncologist also says that the PSA will most likely rise when I stop the hormone in 2010.
Best of luck to you and wishes for continued good news.
